Do I Have Lazy Eye? How Can This Be Fixed?

You have left upper eyelid ptosis.  It may also correlate with bony facial asymmetry, with left side of your face being smaller than the right side (although hard to to tell from your cropped photo).  There are surgical options to improve the symmetry of the eyelids.  Consult an oculoplastic surgeon.

As Dr. Steinsapir has mentioned, you have mild left upper eyelid ptosis. In addition, you have mild brow asymmetry, with the left side being lower. It is not unusual for patients to have a degree of right/left asymmetry, and I would suspect that there is an underlying bony asymmetry as well.

Lazy eye is a lay term for amblyopia.  The lack of visual development in one of the eyes from infancy results in the eye turning in or out.  Treatment for amblyopia is early childhood patching and when necessary eye muscle surgery to correct eye alignment.  This is not what you appear to have.  What you have going on is upper eyelid ptosis of the left eye.  Consider seeing an oculoplastic surgeon for this condition.  Kevin Perlman, M.D. in Washington DC would an excellent choice.  The American Society for Ophthalmic Plastic and Reconstructive Surgery maintains a geographic directory that can also help you find a well qualified surgeon ( ASOPRS dot org).
